"Man City are the sort of team that will win 4-0 and then lose 5-0 away,” Sutton told Metro.co.uk. "But I think they will go furthest – they made a big statement by beating Chelsea and the manner which they beat Chelsea.

"In my mind there were question marks over them defensively last season and had they lost that game to Chelsea then people would be asking questions so I think they made a bit of a statement in that respect. On their day City are up there with the best.”

Sutton also believes that Liverpool - two draws from their opening two group matches - can spring a surprise later in the tournament.

However, he doesn’t feel Jurgen Klopp’s men are potential winners due to a familiar problem.

"I love watching Liverpool play. It’s just the same old Liverpool – so exciting to watch going forward but they just have that vulnerability at the back. They can’t win the Champions League but they could cause an upset on the way."
